(Cl. 122-494) ABSTRACT F THE DISCLOSURE A burner base for a gas boiler is provided with a main body having bottom, opposite side and rear walls. The front and top of the base are open, and spanning the opposite side walls olA the base is a crossbar for supporting a gas burner assembly. The main body of the base and the cross bar are made of sheet metal.

vThis invention relates generally to gas boilers and particularly to a burner basefor a gas boiler. l

Boilers for hot water heating systems customarily are provided with boiler sections made of cast iron. The boiler is quite heavy and must be supported upon a base which is very rugged, The gas burners commonly are housed in a gas burner drawer which is slidably mounted in the base. This arrangement has not proved to be entirely satisfactory because it is to complicated and expensive. Accordingly, an important object of this invention is to provide a burner base which houses the burners without the benet of a gas burner drawer, and which does not sacrice any substantial advantage afforded by such adrawer.

Another object is to provide such a base which is simple in design, simple and comparatively inexpensive to manufacture and rugged in service.

Another object is to provide such a base which meets the most rigid safety requirements of the industry.

Other objects of the invention will become apparent when the following description is read with reference to the accompanying drawings, wherein:

FIGURE 1 is a plan view of a burner base constructed in accordance with the invention, showing in phantom the gas burners, mixing tubes and gas manifold;

FIGURE 2 is a side view; Y

FIGURE 3 is a front view, showing in phantom the water boiler, gas burners and mixing tubes;

FIGURE 4 is a section on line IV-IV in FIGURE 1;

FIGURE 5 is a section on line V-V in FIGURE 2;

FIGURES 6, 7 and 8 are side views of the burner base, with parts broken away to expose a gas burner and its mixer tube, and to show progressive positions thereof as they are removed from the burner base; and

FIGURE 9 is a side view of the burner base, with parts broken away to expose a gas burner and its mixer tube, and to show the burner, its mixer tube and the gas manifold as they are removed from the burner base.

The following description is directed to the specific form of the invention shown in the drawings and is not addressed to the scope of the invention, which may be practiced in a variety of forms.

The burner base comprises a main body part, generally designated 10. The main body part includes a first sheet metal member 12 providing a horizontally extending bottom wall 14, upright opposite side walls 16 turned upwardly from the bottom wall 14 and horizontally extending flanges 18 turned outwardly from the side walls 16. The member 12 also provides a flange 20 L- shaped in transverse section and turned outwardly at the front end of each side wall 16, a flange 22 turned inwardly at the rear end of each side wall 16 and a tlange 24 L-shaped in transverse section and turned upwardly ice at the front end of the bottom wall 14, being disposed in forwardly spaced relation to the ilanges 20. The main body part also includes a second sheet metal member 26 providing an upright rear wall 28 abutting the flanges 22, a horizontally extending flange 30 turned forwardly from the rear wall 28 and underlying the bottom wall 14, a flange 32 turned forwardly from each end of the rear wall 28 and disposed in outward spaced relation to the associated side wall 16, and a horizontally extending flange 34 turned rearwardly from the rear wall 28. The llanges 22 of the side walls 16 are welded to the rear wall 28, and thc flange 30 of the rear wall is welded to the bottom wall 14 whereby to afford a main body part which is rigid and extremely rugged. The bottom wall 14 is lined with insulation, designated 3S, and is maintained in spaced relation to an underlying supporting surface by four legs 36 formed as shown of sheet metal and welded to the side walls 16 and bottom wall 14.

Extending across the main body part l()l is a crossbar 38 disposed in overlying spaced relation to the bottom wall 14 and in forward spaced relation to the rear wall 28. The crossbar is a sheet metal member U-shaped in transverse section, being provided with a side wall 40 having flanges 42 respectively at opposite ends of the crossbar, and with a side wall 44 having flanges 46 respectively at opposite ends of the crossbar. The flanges 42 and 46 are welded yto the side walls 16. The side wall 40is provided with a deep recess 48 for each mixer tube, each recess terminating at each end in a stepped shoulder 50.

Extending forwardly from each side wall 16 is a plate bracket 52. The rear edge of the bracket 52 is deeply recessed, as at 54. The bracket is secured to the side wall 16 by bolts 56 and 58, the latter extending through an elongated opcn slot 60. The front of the bracket is recessed, as at 62, for a purpose to appear.

Referring particularly to FlGURES 3, 4 and 5, seated respectively upon flanges 18 of side walls 16 ofthe burner base are legs 64 of a cast iron water boiler', generally designated 66. The bottom of thc boiler, between the legs 64, is raised above the plane of the flanges i8, as at 68. Bolts (not shown) extending through tlrc legs 64 and through openings in the llanges 18 secure the boiler to the burner base. Underlying the boiler are a pair of gas burner assemblies each comprising a burner 72 seated upon the rear end of a mixer tube 74 and extending forwardly to the front of the burner base. The open front end of the mixer tube is provided with a shutter 76 tted over a mixer pipe 77 projecting from a manifold pipe 78 extending across the front of the burner base and affixed to brackets 52, as by welding. The front end of the mixer tube 74 is carried by the mixer pipe 77 projecting from the manifold pipe 78, while the rear end of the mixer tube is carried by the crossbar 38. For this purpose, the bottom of the mixer tube is provided with a lug formation, generally designated 80, having a main body part 82 from which depends a part 84. The part 84 extends downwardly between the side walls 40 and 44 of thc crossbar 38 and secures the burner assembly against displacement fore and aft, while the part 82 is seated in the recess 4S and secures the burner assembly against displacement laterally.

The weight of the boiler 66 is transmitted through thc main body part l0 ofthe burner base to the legs 36 underlying the same. The flanges 2t) and 32 stillen the side walls 16 and rear wall 28 sutliciently to withstand the load.

Referring particularly to FIGURES 6-8, a gas burner assembly is removed from the burner base by first tilting the burner 72 and mixer tube 74 as a unit upwardly and forwardly (FIGURE 6) till the lug part 84 is removed from between the walls 40 and 44 of the crossbar 38. Then the assembly is moved rearwardly (FIGURE 7) to dis- 3 engage the shutter 76 from the mixer pipe 77. Finally, the assembly is pulled out through the front of the burner base, across the manifold (FIGURE 8). To replace the burner this procedure is reversed.

To remove the manifold with the gas burner assembly, bolts 56 are removed and bolts 58 are loosened. Thereupon, the burner assembly and manifold 78 are tilted upwardly and forwardly and raised as a unit till the lug part 84 is removed from between the walls 40 and '44 of the crossbar 38 and thebolts 58 are disengaged from slots 60 in the brackets 52. The burner assembly and manifold are then pulled out through the front of the burner base as a unit (FIGURE 9).

v It will be understood, of course, that although two burner assemblies have been shown in the drawings, the number of such assemblies is optional.
